SUBSTANTIA Density Treatment

Pre-Shampoo Treatment for Fine, Thinning & Mature Hair

125 mL

Your hair changes. Your care should too.

As hair changes over time, it often becomes finer, more fragile and loses some of its natural body and resilience. While many products focus on dryness or damage, comparatively few are developed specifically for mature hair and scalp.

SUBSTANTIA was created for those changes.

Developed specifically for fine, thinning and mature hair, this lightweight pre-shampoo treatment prepares the hair before cleansing—when it is most vulnerable to friction and breakage. By conditioning before shampooing rather than after, it supports softer, smoother and more manageable hair while helping restore body, natural movement and the feeling of more substantial hair.

Formulated with Tasmanian Kelp Cellular Extract, Amaranth Biopeptides and carefully selected botanical ingredients, every ingredient has earned its place in the formulation.

Designed for weekly use, or as needed, it complements your existing haircare routine with a more considered approach to caring for hair as it changes over time.

The Benefits

• Helps hair feel fuller and more substantial

• Supports softness, strength and resilience

• Helps reduce friction during washing

• Enhances natural body, movement and shine

• Lightweight conditioning without heaviness or build-up

• Designed for weekly use, or as needed
